@@ -17,6 +17,8 @@ Ce projet est un POC de professeur virtuel pour enfants, avec:
 - Le backend a un socle d'authentification avec comptes `users`, roles `student`, `teacher`, `maintenance`.
 - Le compte admin/prof initial est seede depuis `.env` via `ADMIN_USERNAME` et `ADMIN_PASSWORD`.
 - Le login pose un cookie HTTP-only `professeur_top_session` et renvoie aussi un token bearer.
+- Le frontend affiche maintenant une page de connexion avant l'application et verifie la session via `/auth/me`.
+- Apres connexion admin/prof, l'interface actuelle reste accessible avec un bouton de deconnexion.
 - Le vrai `docker-compose.yml` de production n'est pas dans ce repo. Il est situe un niveau au-dessus sur le serveur.
 - La conf nginx reelle route:
   - `/api/` vers `tutor-backend:8000`
